The division has posted rate proposals from a total of 16 conventional carriers and two new CO-OP plans for the exchange and non-exchange markets. The division marked proposals from carriers that plan to participate in the state's Cover Oregon health insurance exchange program with asterisks.

Officials expect 12 of the 15 carriers in the individual market and eight of the 14 carriers in the small-group market to sell coverage through Cover Oregon.

The Patient Protection and Affordable Care Act (PPACA) requires the U.S. Department of Health and Human Services (HHS) and state agencies to set up exchanges, or health insurance supermarkets, for individuals and small groups in all 50 states and the District of Columbia by Oct. 1.

Oregon is setting up its own exchange.

A look at individuial exchange plan rates for the Eugene, Ore., area, for example, shows that proposed rates for a mid-tier silver plan for a 21-year-old single non-tobacco user could range from $176 at Moda to $394 at Trillium.

For a single 60-year-old non-tobacco user, silver plan rates could range from $519 per month at PacificSource to $1,070 at Trillium.

In April, Cover Oregon published an initial list of carriers that had suggested that they might participate in the exchange program. Large that have dropped out of the list of contenders include Regence BlueCross BlueShield of Oregon and units of UnitedHealth Group Inc. (NYSE:UNH).

Regence and UnitedHealth will both participate in the state's individual and small-group non-exchange market.

Notable carriers in the individual exchange market will include Kaiser Permanente and Health Net Inc. (NYSE:HNT).

In the state's small-group exchange market, Kaiser Permanente appears to be the best known regional or national player.

Aetna Inc., Cigna Corp., Humana Inc. and WellPoint Inc. are not competing with plans with those brand names in either the exchange market or non-exchange market.

Two "CO-OP" plans -- new nonprofit, member-owned plans brought to life by a provision of CO-OP -- will compete in both the individual exchange market and the small-group exchange market. The CO-OP options are Freelancers Consumer Operated and Oriented Program of Oregon Inc. and Oregon's Health CO-OP.
